The formula for perimeter is:
<span>P = 2 h + 2 w</span>
where P is perimeter = 120 cm, h is height, w is width
we are also given that: h = (2/3) w, therefore:
P = 2 (2/3) w + 2 w = 120
(4/3) w + 2 w = 120
w = 36 cm
Therefore l is:
l = (2/3) w = 24 cm
<span>Hence the dimension should be 24cm by 36 cm</span>

Answer:
C. Parallelogram and rectangle
Step-by-step explanation:
If it was a square...all the sides would be the same, so it cannot be a square, therefore it is not A or B
<span>-1/4y(2y^3 - 8)
= -1/2 y^4 + 2 y</span>
